DETAILED DESCRIPTION

FIGS. 1 through 17, discussed below, and the various embodiments used to describe the principles of this disclosure in this patent document are by way of illustration only and should not be construed in any way to limit the scope of the disclosure. Those skilled in the art will understand that the principles of this disclosure can be implemented in any suitably arranged wireless communication system.

The traditional “Windows, Icon, Mouse, and Pointer” (WIMP) paradigm is configured to provide two-dimensional (2D) inputs for an electronic device. The advent of mobile computing has led to innovations in input and user experience such as multi-touch, styluses, and the like. Similarly, today's Virtual Reality (VR), Augmented Reality (AR), Mixed Reality (MR), Cross/Extended Reality (XR) and/or other computing interfaces require specific remotes and/or controllers for user input that are distinct from traditional computing mice. The existing VR/AR/MR/XR input approaches allow for three-dimensional (3D) manipulation of UI elements, but cannot emulate the precision input of a traditional computing mouse.

Embodiments of the present disclosure provide for a hybrid, multi-mode device that is able to function as both a computing mouse in a 2D environment as well as a VR/AR/MR/XR controller for a 3D environment. The disclosed technology's hybrid system allows for computing experiences which seamlessly leverage both WIMP paradigms as well as new experiences enabled by VR/AR/MR/XR. Certain embodiments provide for VR/AR/MR/XR enhancements such as virtual representations that can be implemented with the device (e.g., virtual graphical icons displayed on the device to augment the device) to improve usability. Embodiments of the present disclosure can provide position/operation mode detection, ergonomics for seamless 2D and 3D gripping by user, 3D tracking for providing virtual representations of the physical device, user hand presence detection, user hand position sensing for providing virtual representation of user interaction, user hand position sensing for grip-dependent functionality and mode switching, 2D and 3D gesture support, as well as other features.

FIG. 1 illustrates an example electronic device in a network environment 100 according to various embodiments of the present disclosure. The embodiment of the electronic device 101 and the network environment 100 shown in FIG. 1 is for illustration only. Other embodiments of the electronic device 101 and network environment 100 could be used without departing from the scope of this disclosure.

According to an embodiment of the present disclosure, an electronic device 101 is included in a network environment 100. The electronic device includes, or is coupled to, an input device 102. The electronic device 101 can include at least one of a bus 110, a processor 120, a memory 130, an input/output (IO) interface 150, a display 160, a communication interface 170, or sensors 180. In some embodiments, the electronic device 101 can exclude at least one of the components or can add another component.

The bus 110 includes a circuit for connecting the components 120 to 170 with one another and transferring communications (e.g., control messages and/or data) between the components.

The processor 120 includes one or more of a central processing unit (CPU), an application processor (AP), or a communication processor (CP). The processor 120 is able to perform control on at least one of the other components of the electronic device 101, and/or perform an operation or data processing relating to communication.

The memory 130 can include a volatile and/or non-volatile memory. For example, the memory 130 can store commands or data related to at least one other component of the electronic device 101. In various embodiments, the memory 130 can store spatial map data that can include mapping information of a real environment such as the interior of an office building, mall, house, amusement park, neighborhood or any other real world or virtual world mapping information utilized by an application 147 on the electronic device 101. According to an embodiment of the present disclosure, the memory 130 stores software and/or a program 140. The program 140 includes, e.g., a kernel 141, middleware 143, an application programming interface (API) 145, and/or an application program (or “application”) 147. At least a portion of the kernel 141, middleware 143, or API 145 can be denoted an operating system (OS).

For example, the kernel 141 can control or manage system resources (e.g., the bus 110, processor 120, or a memory 130) used to perform operations or functions implemented in other programs (e.g., the middleware 143, API 145, or application program 147). The kernel 141 provides an interface that allows the middleware 143, the API 145, or the application 147 to access the individual components of the electronic device 101 to control or manage the system resources.

The middleware 143 can function as a relay to allow the API 145 or the application 147 to communicate data with the kernel 141, for example. A plurality of applications 147 can be provided. The middleware 143 is able to control work requests received from the applications 147, e.g., by allocating the priority of using the system resources of the electronic device 101 (e.g., the bus 110, the processor 120, or the memory 130) to at least one of the plurality of applications 147.

The API 145 is an interface allowing the application 147 to control functions provided from the kernel 141 or the middleware 143. For example, the API 145 includes at least one interface or function (e.g., a command) for filing control, window control, image processing, or text control.

The IO interface 150 serve as an interface that can, e.g., transfer commands or data input from a user or other external devices to other component(s) of the electronic device 101. Further, the IO interface 150 can output commands or data received from other component(s) of the electronic device 101 to the user or the other external device.

The display 160 includes, e.g., a liquid crystal display (LCD), a light emitting diode (LED) display, an organic light emitting diode (OLED) display, or a microelectromechanical systems (MEMS) display, or an electronic paper display. The display 160 is able to display, e.g., various contents (e.g., text, images, videos, icons, or symbols) to the user. The display 160 can include a touchscreen and may receive, e.g., a touch, gesture, proximity or hovering input using an electronic pen or a body portion of the user.

For example, the communication interface 170 is able to set up communication between the electronic device 101 and an external electronic device (e.g., a first electronic device 102, a second external electronic device 104, or a server 106). For example, the communication interface 170 can be connected with the network 162 or 164 through wireless or wired communication to communicate with the external electronic device. The communication interface 170 can be a wired or wireless transceiver or any other component for transmitting and receiving signals, such as video feeds or video streams.

Electronic device 101 further includes one or more sensors 180 that can meter a physical quantity or detect an activation state of the electronic device 101 and convert metered or detected information into an electrical signal. For example, sensor 180 can include one or more buttons for touch input, a camera, a gesture sensor, a gyroscope or gyro sensor, an air pressure sensor, a magnetic sensor or magnetometer, an acceleration sensor or accelerometer, a depth or distance sensor, a grip sensor, a proximity sensor, a color sensor (e.g., a red green blue (RGB) sensor), a bio-physical sensor, a temperature sensor, a humidity sensor, an illumination sensor, an ultraviolet (UV) sensor, an electromyography (EMG) sensor, an electroencephalogram (EEG) sensor, an electrocardiogram (ECG) sensor, an infrared sensor (IR) sensor, an ultrasound sensor, an iris sensor, a fingerprint sensor, and the like. The sensor(s) 180 can further include a control circuit for controlling at least one of the sensors included therein. Any of these sensor(s) 180 can be located within the electronic device 101. A camera sensor 180 can capture a plurality of frames for a single image to be combined by the processor 120.

The input device 102 is configured to detect a user motion and provide a corresponding command signal to the electronic device 101. For example, in response to a movement of the input device 102 by a user, the electronic device 102 communicates the command signal corresponding to the movement of the input device 102 to the electronic device 101. Additionally, an engagement, such as a pressing, of a button on the input device 102 can trigger a communication of the command signal. In certain embodiments, the input device 102 includes a touch pad and, in response to interactions with the touch pad, the input device 102 communicates the command signal. In response to the command signal, the electronic device 101 performs one or more functions. In certain embodiments, the input device 102 is coupled to the electronic device 101 via a wireless connection, such as a near-field connection such as BLUETOOTH, ZIGBEE, and the like, a magnetic connection, or an optical communication. In certain embodiments, the input device 102 is coupled to the electronic device via a wired or wireline connection.

In certain embodiments, an external electronic device, such as a wearable device or an electronic device 101-mountable wearable device (e.g., an optical head mounted display (HMD)) is provided. When the electronic device 101 is mounted in the HMD, the electronic device 101 detects the mounting in the HMD and operate in an augmented reality mode. In certain embodiments, the electronic device 101 detects the mounting in the HMD and operate in an augmented reality mode. When the electronic device 101 is mounted in the HMD, the electronic device 101 communicates with the HMD through the communication interface 170. The electronic device 101 can be directly connected with the HMD to communicate with the HMD without involving a separate network.

The wireless communication is able to uses a wireless communication medium, such as at least one of, e.g., long term evolution (LTE), long term evolution-advanced (LTE-A), 5th generation wireless system (5G), mm-wave or 60 GHz wireless communication, Wireless USB, code division multiple access (CDMA), wideband code division multiple access (WCDMA), universal mobile telecommunication system (UMTS), wireless broadband (WiBro), or global system for mobile communication (GSM), as a cellular communication protocol. The wired connection can include at least one of universal serial bus (USB), high definition multimedia interface (HDMI), recommended standard 232 (RS-232), or plain old telephone service (POTS).

The network 162 includes at least one of communication networks. Examples of communication include a computer network (e.g., local area network (LAN) or wide area network (WAN)), Internet, or a telephone network.

The external electronic devices 104 and server 106 each can be a device of the same or a different type from the electronic device 101. According to certain embodiments of the present disclosure, the server 106 includes a group of one or more servers. According to certain embodiments of the present disclosure, all or some of operations executed on the electronic device 101 can be executed on another or multiple other electronic devices (e.g., the electronic device 104 or server 106). According to certain embodiments of the present disclosure, when the electronic device 101 should perform some function or service automatically or at a request, the electronic device 101, instead of executing the function or service on its own or additionally, can request another device (e.g., electronic device 104 or server 106) to perform at least some functions associated therewith. The other electronic device (e.g., electronic device 104 or server 106) is able to execute the requested functions or additional functions and transfer a result of the execution to the electronic device 101. The electronic device 101 can provide a requested function or service by processing the received result as it is or additionally. To that end, a cloud computing, distributed computing, or client-server computing technique can be used, for example.

Although FIG. 1 shows that the electronic device 101 includes the communication interface 170 to communicate with the external electronic device 104 or server 106 via the network 162, the electronic device 101 can be independently operated without a separate communication function, according to an embodiment of the present disclosure.

The server 106 can support to drive the electronic device 101 by performing at least one of operations (or functions) implemented on the electronic device 101. For example, the server 106 can include a processing module or processor that may support the processor 120 implemented in the electronic device 101.

For example, the electronic device 101 can include an event processing module, such as within processor 120. The event processing module can process at least part of information obtained from other elements (e.g., the processor 120, the memory 130, the input/output interface 150, or the communication interface 170) and can provide the same to the user in various manners. The server event processing module can include at least one of the components of the event processing module and perform (or instead perform) at least one of the operations (or functions) conducted by the event processing module.

For example, according to an embodiment of the present disclosure, the event processing module processes information related to an event, which is generated while the electronic device 101 is mounted in a wearable device (e.g., the electronic device 102) to function as a display apparatus and to operate in the augmented reality mode, to fit the augmented reality mode and display the processed information. When the event generated while operating in the augmented reality mode is an event related to running an application, the event processing module can block the running of the application or process the application to operate as a background application or process. Additional information on the event processing module 185 may be provided through FIG. 2 described below.

The event processing module can be separate from the processor 120 or at least a portion of the event processing module can be included or implemented in the processor 120 or at least one other module, or the overall function of the event processing module can be included or implemented in the processor 120 shown or another processor. The event processing module can perform operations according to embodiments of the present disclosure in interoperation with at least one program 140 stored in the memory 130.

FIG. 2 illustrates an example electronic device 220 according to various embodiments of the present disclosure. The embodiment of the electronic device 220 shown in FIG. 2 is for illustration only. Other embodiments of electronic device 220 could be used without departing from the scope of this disclosure. The electronic device 220 depicted in FIG. 2 can be configured the same as, or similar to, any of electronic devices 101, 102, or 104.

FIG. 2 is a block diagram illustrating an example configuration of an electronic device according to an embodiment of the present disclosure. Referring to FIG. 2, the electronic device 220 according to an embodiment of the present disclosure can be an electronic device 220 having at least one display. In the following description, the electronic device 220 can be a device primarily performing a display function or can denote a normal electronic device including at least one display. For example, the electronic device 220 can be an electronic device (e.g., a smartphone) having a touchscreen 230.

According to certain embodiments, the electronic device 220 can include at least one of a touchscreen 230, a controller 240, a storage unit 250, or a communication unit 260. The touchscreen 230 can include a display panel 231 and/or a touch panel 232. The controller 240 can include at least one of an augmented reality mode processing unit 241, an event determining unit 242, an event information processing unit 243, or an application controller 244.

For example, when the electronic device 220 is mounted in a wearable device 210, the electronic device 220 can operate, e.g., as an HMD, and run an augmented reality mode. Further, according to an embodiment of the present disclosure, even when the electronic device 220 is not mounted in the wearable device 210, the electronic device 220 can run the augmented reality mode according to the user's settings or run an augmented reality mode related application. In the following embodiment, although the electronic device 220 is set to be mounted in the wearable device 210 to run the augmented reality mode, embodiments of the present disclosure are not limited thereto.

According to certain embodiments, when the electronic device 220 operates in the augmented reality mode (e.g., the electronic device 220 is mounted in the wearable device 210 to operate in a head mounted theater (HMT) mode), two screens corresponding to the user's eyes (left and right eye) can be displayed through the display panel 231.

According to certain embodiments, when the electronic device 220 is operated in the augmented reality mode, the controller 240 can control the processing of information related to an event generated while operating in the augmented reality mode to fit in the augmented reality mode and display the processed information. According to certain embodiments, when the event generated while operating in the augmented reality mode is an event related to running an application, the controller 240 can block the running of the application or process the application to operate as a background process or application.

More specifically, according to an embodiment of the present disclosure, the controller 240 can include at least one of an augmented reality mode processing unit 241, an event determining unit 242, an event information processing unit 243, or an application controller 244 to perform functions according to various embodiments of the present disclosure. An embodiment of the present disclosure can be implemented to perform various operations or functions as described below using at least one component of the electronic device 220 (e.g., the touchscreen 230, controller 240, or storage unit 250).

According to certain embodiments, when the electronic device 220 is mounted in the wearable device 210 or the augmented reality mode is run according to the user's setting or as an augmented reality mode-related application runs, the augmented reality mode processing unit 241 can process various functions related to the operation of the augmented reality mode. The augmented reality mode processing unit 241 can load at least one augmented reality program 251 stored in the storage unit 250 to perform various functions.

The event detecting unit 242 determines or detects that an event is generated while operated in the augmented reality mode by the augmented reality mode processing unit 241. Further, the event detecting unit 242 can determine whether there is information to be displayed on the display screen in relation with an event generated while operating in the augmented reality mode. Further, the event detecting unit 242 can determine that an application is to be run in relation with an event generated while operating in the augmented reality mode. Various embodiments of an application related to the type of event are described below.

The event information processing unit 243 can process the event-related information to be displayed on the display screen to fit the augmented reality mode when there is information to be displayed in relation with an event occurring while operating in the augmented reality mode depending on the result of determination by the event detecting unit 242. Various methods for processing the event-related information can apply. For example, when a three-dimensional (3D) image is implemented in the augmented reality mode, the electronic device 220 converts the event-related information to fit the 3D image. For example, event-related information being displayed in two dimensions (2D) can be converted into left and right eye information corresponding to the 3D image, and the converted information can then be synthesized and displayed on the display screen of the augmented reality mode being currently run.

When it is determined by the event detecting unit 242 that there is an application to be run in relation with the event occurring while operating in the augmented reality mode, the application controller 244 performs control to block the running of the application related to the event. According to certain embodiments, when it is determined by the event detecting unit 242 that there is an application to be run in relation with the event occurring while operating in the augmented reality mode, the application controller 244 can perform control so that the application is run in the background so as not to influence the running or screen display of the application corresponding to the augmented reality mode when the event-related application runs.

FIG. 3 is a block diagram illustrating a program module according to an embodiment of the present disclosure. The embodiment illustrated in FIG. 3 is for illustration only and other embodiments could be used without departing from the scope of the present disclosure. In the example shown in FIG. 3, although an augmented reality (AR) system is depicted, at least some embodiments of the present disclosure apply equally to virtual reality (VR) and augmented reality (AR). Referring to FIG. 3, the program module can include a system operating system (e.g., an OS) 310, a framework 320, and an application(s) 330.

FIGS. 4A and 4B illustrate input devices according to this disclosure. The embodiments of the input devices 405 a and 405 b are for illustration only and other embodiments could be used without departing from the scope of the present disclosure.

A 2D input device 405 a, such as what is commonly referred to as a “mouse”, is configured to rest on a tactile surface, such as a surface of a desk, table, or other suitable flat and substantially horizontal surface. The 2D input device 405 a converts lateral motion (in two dimensions), such as movement right, left, upward (away from an operator), downward (towards the operator), or diagonally, into respective command signals for manipulating one or more objects, such as a cursor or icon, on a screen of the electronic device 101 to which the 2D input device 405 a is coupled. In certain embodiments, the 2D input device 405 a includes one or more buttons such as a first data button 410, a second data button 415, and a scroll wheel 420 to provide commands to the electronic device, such as a command to open or execute a particular application. The 2D input device 405 a is configured to provide 2D inputs to the electronic device 101. That is, the input device 405 a is configured to detect motion in two dimensions and manipulate the cursor or icon in two dimensions.

A 3D input device 405 b is configured to be held by an operator, such as away from a surface of a desk, table, or other suitable flat and substantially horizontal surface. The 3D input device 405 b is able to track certain objects through at least three-degrees of freedom (3DOF). The 3D input device 405 b includes sensors which track 3 or more degrees of freedom (DOF), such as 6DOF, typically orientation. The 3D input device 405 b converts motion (in three dimensions), such as movement horizontally right, horizontally left, horizontally upward (away from an operator), horizontally downward (towards the operator), vertically upward (away from the surface or ground), vertically downward (towards the surface or ground), diagonally in any combination of the aforementioned directions, or rotationally, into respective command signals for manipulating one or more objects in a 3D environment on a screen of the electronic device 101 to which the 3D input device 405 b is coupled. In certain embodiments, the 3D input device 405 b includes a touch surface 425 and one or more buttons 430 to provide additional commands to the electronic device, such as a command to open or execute a particular application.

In the age of spatial computing, users with computers running VR/AR (and/or MR/XR) environments may require both computing mice, such as 2D input device 405 a, as well as VR/AR controllers, such as 3D input device 405 b. Such environments may often require users to frequently switch between input devices, or such otherwise environments may fall short when attempting to provide 2D precision using a 3D controller (or vice-versa).

VR also brings about unique challenges for the 2D input device 405 a due to the inability for users to directly see the 2D input device 405 a, such as while users are wearing VR headsets. This makes simple tasks, such as locating the 2D input device 405 a or coordinating hand motions to buttons 410, 415 on the 2D input device 405 a, more difficult. Many of these challenges have been addressed for 3D input device 405 b (VR controllers) but not for traditional input devices.

Embodiments of the present disclosure provide a hybrid, multi-mode input device that is able to function as both a 2D input device, such as a computing mouse, as well as a 3D input device, such as a VR/AR/MR/XR controller. The hybrid, multi-mode input device enables computing experiences that seamlessly leverage both WIMP paradigms as well as new experiences enabled by VR/AR/MR/XR.

Certain embodiments can reduce the number of required input devices, thus decreasing the need to switch devices, and also improving portability. Certain embodiments can enable new workflows that seamlessly transition between multiple modalities, such as dragging from 2D mouse to 3D workspace. Certain embodiments can further improve the user experience of computing mouse operations through VR representations of the device and finger/grip positioning.

The via 725 is dimensioned to enable the contoured housing 705 to be ergonomically comfortable to a user when a hand of the user is gripping the multi-mode input device 700. For example, the via 720 can be dimensioned to accommodate one or more of the fourth digit (namely, the “ring finger”) and the fifth digit of the hand of the user while the user is holding the multi-mode input device 700 within the hand of the user. That is, when the user grips the multi-mode input device 700 and lifts the multi-mode input device 700 away from a tactile surface, such as a surface of a desk or table, a hand of the user envelopes and grips the multi-mode input device 700 such that one or more fingers of the hand engage the switch 730 and fit partially within the via 725. For example, as a user picks-up the multi-mode input device 700, one or more fingers engage a lever arm of the switch 730, depressing the lever arm inwards toward the via 725 enabling the user to grip the contoured housing 705 and lever arm of the switch 730 within the hand of the user.

The processor, such as processor 525, is able to detect that the switch 730 is engaged and determines that the multi-mode input device 700 is to operate in a 3D mode. For example, when the user picks-up the multi-mode input device 700 and engages (i.e., presses) the lever arm of the switch 630, the switch 630 can transmits a signal to the processor 525 indicating that the multi-mode input device 700 is gripped in a hand of the user and is to operate in the 3D mode as a 3D controller. In certain embodiments, the processor 525 detects that the lever arm of the switch 730 has been engaged. For example, the lever arm of the switch 730 may close an electrical circuit to which the processor 525 also is coupled. When the lever arm of the switch 730 is engaged, the movement of the lever arm opens the circuit. Thereafter, the processor 525 detects the open circuit, such as by detecting an interruption in a current flow.

FIG. 8 illustrates another multi-mode input device according to embodiments of the present disclosure. The embodiment of the multi-mode input device 800 is for illustration only and other embodiments could be used without departing from the scope of the present disclosure.

The contoured housing 805 includes a top surface. The top surface is dimensioned to fit comfortably when a hand of the user is resting on the top surface. That is, the top surface is ergonomically designed to fit within a palm of the hand of the user when the hand of the user is resting upon the multi-mode input device 800. The contoured housing 805 also includes a bottom surface that is substantially flat. That is, the bottom surface is flat but may include one or more glides that may protrude from the flat bottom surface. Additionally, the contoured housing 805 may include one or more indentions, such as configured to enable access to a battery compartment or a charge port. The bottom surface may also include an optic sensor, or track ball, configured to detect or measure lateral motion of the multi-mode input device 800 along a tactile surface, such as a surface of a desk or table. Therefore, the bottom surface is flat, but may have one or more protrusions or indentions, thus rendering the bottom surface substantially flat. The contoured housing 805 is dimensioned such that a width 820 of the multi-mode input device 800 enables the multi-mode input device 800 to comfortably fit between a thumb and a fifth digit of a hand of the user. The contoured housing 805 also includes a via 825. The via 825 is dimensioned to enable the contoured housing 805 to be ergonomically comfortable to a user when a hand of the user is gripping the multi-mode input device 800. For example, the via 820 can be dimensioned to accommodate one or more of the second digit (namely the “pointer finger”), the third digit (namely the “middle finger”), the fourth digit, and the fifth digit of the hand of the user while the user is holding the multi-mode input device 800 within the hand of the user. That is, when the user grips the multi-mode input device 800 and lifts the multi-mode input device 800 away from a tactile surface, such as a surface of a desk or table, a hand of the user envelopes and grips the multi-mode input device 8700 such that one or more fingers fit partially within or through the via 825.
